This problem just started occuring with Premiere 6.5 and I'm not sure what could have caused it, although I think it may have begun shortly after my most recent windows update any case, whenever I try to adjust the in or out point of a clip on the timeline by sliding it in or out, Premiere crashes instantaneously and closes. This also happens when I attempt to drag the edit line over a clip with an unrendered video effect. Any advice on what to do?
